Livability to speed between 34ft -ish monohull and catamaran

[pironiero]

Hey doods, its me again with a new question
Here it goes

If we were to compare some 34ish feet long monohull, built with FG samwich, scow bow, carbon mast and flat belly(all that good stuff) with same size catamaran built using same tech and rigging- what will be faster and more liveable overall at the end?

i know its a stooped questione, but please be patient.

Whatever do you mean by livable? Faster has some hope of being quantified. BBQ? Dinghy on davits? Full gourmet galley? Plush staterooms? Hot water? Babe/boi magnet?

For a 34 foot cat to be fast it has to be very light. Investigate the Reynolds 33. Enough room to camp not glamp. It will spank most any mono of similar length in most conditions quite handily. For a cat to be really liveable and perform decently it needs to be closer to 45ish feet. Your 34 foot mono can pack in lots more comfort but won't be particularly fast. There are some fairly fast mid 30ish monos out there but not really aimed at "comfort." Woods has a couple cats of that size that might fit the bill but they aren't what you'd call " fast."

 

[Veeger]

You're right. It is sort of a stoopid question. You have to define livable first. Then you have to elaborate on 'faster'. Empty? 1 knot? 0.1 knot? Upwind? Downwind?

I had a 38' cat that was pretty close in concept to your proverbial 34'er. It was livable. I.e. it had a galley, fridge, head, separate shower, 2 queen berths, etc. By most people's standards, the newest Beneteau 34.1 is likewise 'livable' and probably more in keeping with folks expectations than the cat.

Fast? Or fun to sail? This obsession with 'fast' in a moderate sized cruising boat is totally misguided. A couple more knots? Why? Go buy a powerboat. Most 34'ers are even more livable than a 34' sailboat--mono or multi.

Oh... you were just working a tired old forum topic. Sorry.

Carry on.

Whatever do you mean by livable?

its basically means standing headroom(≥190cm), and being able to comfortably move within a boat

Woods has a couple cats of that size

yeah, I'm watching his YouTube channel, I don't know if its his designs, or generally the size that makes 10m≥ cats look really dangerous to take around the globe.
Dont get me wrong, i adore his creations, being able to get that much space from bhe boat this little is a no small feat, but the looks concern me a bit.

also idk if it would be better to make two really fat hulls so the cat will be able to plain(i think without a keel it may work and as an added benefit you'll get more space inside, or maybe, you know, im full of shit, idk)

Dear Mr. Pioniero, you seem to have made a quantum leap to "around the globe." If that is your goal then you need to reconsider your criteria. Fast and comfortable, 35 feet as well as capable of circling the globe? Hate to be a party pooper but, with all due respect, that's like asking for an RV that can also participate in F1 races while the wife prepares fondue in the back. And yes sir, you are most certainly full of shit, at least when it comes to boats.

Take a look at the Prout cats, a number of them have done serious ocean cruising & passagemaking, I think a few (or more?) have gone around the world.

They're not inspiring in looks or speed, but they sail well enough and they're quite "livable." We've had several couple friends who did long term cruising / live-aboard the 37 footer.

dude, why are you so uptight? its a hypothetical, chill tf out.

Nah, man, I'm talking hypothetical, I have no intensions for buying a cat or god forbid build one.
I'm just interested in yours, forum people thoughts about what if two types of vessels, built using same lightweight technology that is widely available in our time, were being compared in overall speed and livability

34' scow bow cruiser with a carbon mast? sounds like a fevered dream.

 

[Gigantasy]

JPK 1030 is 33’11” is very fast and looks pretty big on the inside.

Side note: of the factors in this thought exercise that may be worth establishing is headroom required. Size matters…

 

[El Borracho]

Headroom is really highest on the requirements for livability? Being 5’ 17” myself the only 34 footers, mono or multi, I might stand upright in are desperately ugly and slow. Not on my list of requirement at all.

Far more important for long range livability is interior layout. Primarily proper galley and nav workstations for all conditions. And huge dedicated interior storage spaces for all the sailing and cruising gear. For speed (and just fun sailing) all the freight must be below decks. Those are the Borracho rules, anyway.

Keep in mind that our friend here has escaped Russia for a better life. Give him a break

 

[smj]

In a cat that size for performance and good accommodations I would look at the Tek (Shuttleworth) 35. They don’t have a bridgedeck cabin which is a turn of for some, but have done numerous ocean crossings and are quite fast.

34' scow bow cruiser with a carbon mast

yeah, that the one non hypothetical part of this whole thing, im going to build classe 950 scow

lmao, thanks

kind of, yeah, cus im 6ft or 184 in cm

 

[Mitre cut]

A lot of that answer is in where are you sailing? If it's a warm place a cat is the better choice - more outdoor and overall space particularly if you get clever with the fabric cockpit enclosures. If you like to cruise where icebergs breed a mono is probably the answer, no need to go outside and much easier to keep warm.

 

[lakeneuch]

If you want fast and cruising in this size range trimarans probably beat both cats and monos in most conditions. Monos have a slight advantage in some wave conditions for speed, and when you want fast in a a tri of this size monos have an advantage with regards to staying the right side up. A production Dragonfly 32 will capsize if you do it wrong, and it will go fast if you do it right. I met a guy who went to iceland last season in one of these from Europe, when you can choose the weather for the necessary 200 to 300 mile hops this is probably the fastest AND most confortable way to get to iceland in a 32 foot boat.

That boat is pretty neat!
